Plasticizers for Biopolymer Films - Glass Transition and
Plasticizers are important additives that diminish the brittleness and impart adequate flexibility and processability to polymers. Plasticizers are low molecular weight agents added to polymeric materials such as plastics, biopolymer based films, paints, or adhesives, to produce or promote plasticity, flexibility, processability and to reduce
Natural-based plasticizers and biopolymer films: A review
Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides. PVC processing is by far the most important use of plasticizers, consuming over 80% of production [3], [4].

- Which plasticizers are used in biopolymer-based films?
- In the formation of biopolymer-based films, food-grade plasticizers are usually used such as glycerol, polyethylene glycol (PEG), and sorbitol etc. Literature review showed that the incorporation of plasticizers increased the EAB and decreased the TS of the biopolymers (125).
- What are biodegradable plasticizers?
- Biodegradable plasticizers such as soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were added to poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films, enhancing their thermal and mechanical properties. TEC or DBP presented better plasticizing effects than SO and ESO for PHBV .
- Why are biopolymer-based films used in industrial applications?
- In recent years, applications of biopolymer-based films have rapidly increased for industrial applications due to their attractive properties, including nutrition value, improved mechanical and functional properties, biocompatibility and biodegradability, and source renewability and eco-friendly nature advantages.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- How does the type of plasticizer affect biopolymer properties?
- The type of plasticizer can strongly affect the barrier properties, water uptake, and mechanical properties of the biopolymer.
- What are biopolymer-based Active packaging films?
- Biopolymer-based active packaging films have attracted increasing attention for packaging applications to meet consumers’ demand of “all natural” food products and the industrial drive of providing “clean-label” products.
